11, claims. v(o1- 2554-62) My invention relates to Vcarpet stretchers of the particular type covered by U. S. Letters Patent No. 1,766,423 issued to me June 24, 1930; also Letters Patent No. 2,108,506 issued to John C.
Owens, February 15, 1938, also Patent No. 2,326,`
117 issued to me Augustk 10, 1943, of which, this application is a continuation in part.
The principal objects of my invention are, to
disclosed in the aforesaid patents, to provide improved means forimparting forward movement to the carpet engaging head of the device during stretching operations, to provide simple and efficient means for maintaining the body of the stretcher in extended position to facilitate the stretching and tacking operations and further, to provide simple and eicient means for releasably connecting the telescoping parts ofthe body of the stretcher.

, drawings, particularly the construction illustrated4 -generally improve andsimplifyfthe constructions Referring by numerals to the accompanying in Figs. 1 to '7 inclusive,j Ill designates a tube which may be .of any desired and `convenient length, and arranged to telescope said tube is a slightly smaller tube II, to the outer end of which is connected by verticalpivot I2 a block I3 that is adapted to bear against the base board or wall of the room in which the carpet stretcher is used. x
To maintain the tubes IIJ and II in.V their different telescopic adjustments, ya U-shaped spring is positioned within the smaller `tube II and projecting in opposite directions .from the ends of the legs of said spring are studs Illa which pass through apertures I Ia in tube II kand the projecting portions of said studs are adapted to enter apertures IllbV that are formed in the outer tube I0. y
The apertures Ib are countersunk in order that the projecting ends of the studs Illa may beY readily engaged and pressed inwardly by the thumb and finger so as to enable the tubes to be moved longitudinallyindependently of each other. H f
The forward end of tube I0 is secured in any suitable manner to a lug I4 that is formed. on the rear end of a frame that comprises a pair of parallel channel bars I5 arranged withvtheir flanges inwardly .presented and the rear ends of said channel bars being integrally connected by a cross piece I6.

.Arranged for sliding movement against the innerY faces of the webs of the channel bars I5 between the flanges thereof are parallel bars I8 and the forward ends of. these bars .are rigidly connected to the main body or vhousing I9 of a head, which housing is substantially rectangular in form and provided with an open bottom.
Arranged to slide freely lengthwise between those portions ofthe Vbars rI8 -that extend into the frame comprising the channels I5 and supported by the inner portions of the lower flanges on said channel bars I5 is a block 20, the forward portion of which is provided with a vertically disposed slot 2|.
slot 2I are ears 22 provided with apertures 23.
Passing through the apertures 23 is a transversely disposed pin or bolt 24 and mounted on the ends thereof that project beyond the ears 22 ars rollers 25 that bear 'on the upper surfaces of the channel bars I5.
A cross piece I1 is formed inv tegral with .and connects theforward portions of Projecting upwardlyy from the l forward portions of the walls to the sides of Pivotally connected by means` of a pin 3B to lever 26 .a short distance rearwardly from the I5 and having their rear ends pivotally conwall adjacent the edge of the carpet that has 'been secured to the floor and with the head of the f stretcher, the housing I9, positioned on top of the carpet adjacent the wall opposite the wall against which block I3 is positioned.
Before beginning the-stretching operation, the hand lever 21 is swung upwardly and forwardly into a substantially vertical position as illustrated by dotted lines in Fig. 2 and under such conditions the head of the stretcher is positioned immediately adjacent the forward end of the frame comprising the channel bars I5, and the links -28 and 3I occupy positions as illustrated by dotted fulcrurn 24 are the forward ends of parallel links 'lines in Fig. 2.
If the carpet that is |being laid is thick or has a heavy nap, then the shaft 35 is rotated so that nected to a transversely disposed pin 32 that isl seated in the rear portions of `said channel bars.
Arranged for vertical movement within housing I9 is a plate 33 in which is seated the upper ends of a series of downwardly and forwardly projecting`v prongs f34.that are 'adapted to engage through th-e action of the slots 42 and pins 44 within the housing I9 so that the prongs 34 will however, the carpet is comparatively thin or of the carpet that'is being stretched by the device,
and extending lengthwise through the center of the housing above this plate 33 is a shaft 35, the ends thereof-being mounted for` rotation in bearings formed in the end walls of housing I9.
One end of this shaft 35 is enlarged in diameter asdesignatedby 36 and a tubular bearing 31 on the end wall of the housing surrounds thisenlarged portioni.' y 5 f Arranged for sliding movement in the enlargedA end portion 36 vof the shaft Ais a diametrically arranged spring pressed pin .38, the outer end of which-is adapted to enter anyon-e of a series of apertures 391 that are formed through the wall of the bearing 31, thus maintaining the shaft 35- at different-points in its rotation.
The apertures 39- in the bearing 31 are countersunkin order that-the end of theY pin maybe engaged and pressed inward when it is desired to partially rotate and adjust the position of shaftl ferentially of the bearing.

It is to be noted that the pivot 32 between the rear ends of the links 3| and the frame of the stretcher and the pivot 29 between the forward end of link 28 and the bars I 8, occupy a horizontal position wholly below the axis 24 of handle 23 andlikewise below the pivotal connection 30 and the point of pivotal connection `betl/eerl link 38 and the forward end of lever 26 thatY forms lapart'of'the handle, andas a position to another, block-26that providesa iul..
crum for the handle slides freely betweenk the rear portions of bars |8 and the .rollers 25 carried by the endsv of fulcrum pin 24A roll on top of the upper flanges of the channel bars I5, thereby materially-reducing friction ofthe cooperating parts while in' action.
In the modified construction illustrated in Figs.
8 to 13 inclusive, a pair of channel bars 5|] are securedto and project rearwardly' from the prong. carrying head Jand arranged-to slide freely through a, bearing 52, formed between said bars is a tube 53. This tube 53 is theouter one of two or more telescopically associated tubes, practically identical with the telescopic tubes l0, H, l2 and I3 showninmy Patent No. 1,766,423 and Vthe inner one. ofthe tubes in the present case,
carrying at its outer end a block (not shown similar to block |1 in said patent.
In Fig. 12, the telescopic. tubes 58 and 59 are shown as being substantially oval in cross section and provided on top with upstanding flanges 60.
Arranged within the inner tube 59 is a transversely disposed spring pressed extensible latch pin 6I, the ends ofwhich are adapted to engage in coinciding apertures formed in the sides of the tubes.
In Fig. 13 the latch consists of a disc 62 having bearings in the outer tube 63 and extending through slots in the inner tube 64, and formed tin said disc are oppositely arranged arcuate slots 65.
Passing through said slots are lpins 66 seated in the inner ends of pins 61, and the latter being adapted to engage in coinciding apertures formed in the tubes and said apertures being reinforced with hard metal rings 68.
A bow spring 69 has its ends seated in pins 61 so as to yieldingly resist inward movement of said pins.
Arranged to move freely between th-e forward portions of the channel bars 50 is a fulcrum block and mounted for operation in anti-friction bearings 14 therein, are the axes 12 of rollers 13 which bear on the lower flanges of the bars 56.
Projecting upwardly from one end of block 16 are ears 15 in which is seated a pin 16 providing a fulcrum for` a hand rlever 11, which occupies a lengthwise position above the bars 50.
The forward end of lever 11 which extends a short distance forwardly of fulcrum 16 is connected to body 5I by a link 18. The rear end of llink. 18. is connected byV a' pivot pin 80 to the forwardA end of tube. 53 and the forward end of' said link f is pivotally connected to Vlever 11a.
